DUS 1707:2017, Standard Test Method for Determination of Vapor Pressure of Crude Oil: VPCRx-F(Tm°C) (Manual Expansion Field Method) (17 pages, in English)
This draft standard test method covers use of manual vapor pressure instruments to determine the vapor pressure of crude oils exerted in a vacuum. This test method is suitable for testing samples that exert a vapor pressure between 25 kPa and 180 kPa at 37.8°C at vapor/liquid ratios from 4:1 to 0.25:1 (X = 4 to 0.25) .
